And therein lies the REAL problem with the placement of Macs in the Workplace: Fear of the Computer Priesthood.
The most common compliant I ever got about Macs is the preference file for iTunes becoming corrupt. Deleting the preference file fixes that problem. But I'm also obligated to remind users of corporate policy that they're not supposed to have terabytes of personal media files on their system. However, it's the PC users who screams bloody murder when the hard drive dies and the only copy of their media library is gone.
Do not even try to deny it. I have had more than one Windows Admin. tell me exactly what you said.
The current network I'm overseeing has 80,000+ workstations. Out of a team of 35 people, one specialist handles ~2,000 Macs workstations and another specialist handles ~2,000 Linux workstations. Everyone else handles Windows workstations. Having one person to handle Macs and/or Linux is fairly typical in most Windows shops I've worked for. If Macs ever did overtake the workplace, I'll get a Mac certification and keep on working.
